Normal roll bond panels have bulges on both sides, but there is also a requirement for one side to remain flat. For example, in the case of a freezer evaporator, this is required for the following reasons. (b) To increase the area of contact with the object to be frozen and increase the freezing effect. (b) To prevent the defrosting tool from getting caught in the bulge during defrosting and damaging the evaporator. (c) To facilitate drainage and cleaning after defrosting and to prevent foreign matter from remaining attached. (d) For aesthetic improvement. (e) To facilitate and ensure surface treatment of the evaporator.

In order to meet the above requirements, conventionally, single-sided bulging roll bond panels have been manufactured by the following method. In other words, a first aluminum plate made of A1100 with an anti-crimping agent interposed in a predetermined form.
A second aluminum plate made of A3003 is superimposed, and the superimposed product is hot-rolled, followed by cold rolling to bond both aluminum plates, and then the first aluminum plate is re-bonded. The first aluminum plate was annealed at a temperature higher than the recrystallization temperature of the second aluminum plate and lower than the recrystallization temperature of the second aluminum plate, and fluid pressure was introduced into the non-crimped portion to bulge only the first aluminum plate side. however,
Since there is a large difference in strength between A1100 and A3003, there was a problem that the rolled product would warp toward the second aluminum plate. In addition, since the difference in recrystallization temperature between A1100 and A3003 is small, it is necessary to perform extremely strict temperature control to anneal only A1100.
It was difficult to manage it.

The method for manufacturing a single-sided bulging roll bond panel according to the present invention involves crimping a first aluminum plate and a second aluminum plate with an anti-crimping agent in a predetermined form, and applying fluid pressure to the non-crimped portions of the plates. In a method for manufacturing a single-sided bulge roll bond panel in which only the first aluminum plate of both aluminum plates is introduced and bulged at the portion, 3.5 to 4.5 wt% of zinc and 0.2 wt% of magnesium are used as the second aluminum plate.
~0.5wt% and has age hardenability, and the first aluminum plate is a non-aluminum alloy having approximately the same strength before age hardening as the aluminum alloy forming the second aluminum plate. The second aluminum plate is made of heat-treated aluminum and subjected to an aging treatment between the annealing process and the swelling process to age-harden the second aluminum plate.

In the above, zinc and magnesium have the property of increasing the strength of an aluminum alloy containing the zinc and magnesium by subjecting it to annealing treatment and then age hardening it. However, if the zinc content is less than 3.5 wt% and the magnesium content is less than 0.2 wt%, no effect of increasing strength due to aging can be expected. In addition, if the zinc content exceeds 4.5wt%, the corrosion resistance of the alloy will deteriorate, and if the magnesium content exceeds 0.5wt%, the corrosion resistance of the alloy will deteriorate.
%, poor bonding between the second aluminum plate and the first aluminum plate made of this alloy will occur. Therefore, the content of zinc and magnesium is 3.5-4.5wt% and 0.2-0.5wt%, respectively.
should be selected within the range.

The reason for using the above-mentioned first aluminum plate and second aluminum plate is as follows. In other words, when comparing the strength of the second aluminum plate before aging treatment and the strength of the first aluminum plate, the difference is small, so there is no risk of warping in the finished product after hot rolling or cold rolling. It is from. In addition, the second aluminum plate has age hardening properties and its strength increases significantly after aging, so the second aluminum plate side does not bulge in the tube expansion process, and as a result, the second aluminum plate This is because the plate may also be annealed, and even if the difference in recrystallization temperature between the second aluminum plate and the first aluminum plate is small, there is no need to strictly control the temperature during annealing. When the aging treatment is applied, the second aluminum plate becomes age-hardened and its strength becomes considerably greater than that of the first aluminum plate, so that when fluid pressure is introduced into the non-crimped part, only the first aluminum plate side bulges out.

According to this invention, since the difference in strength of the aluminum plates before aging treatment is small, warping does not occur when the two are crimped together. Further, the second aluminum plate is hardened after annealing, and its strength becomes greater than that of the first aluminum plate when the tube expands, and only the first aluminum plate side bulges. Therefore, both metal plates may be annealed together, and even if the difference in recrystallization temperature between the two is small, there is no need to strictly control the temperature during annealing as in the conventional method.
